' the same.

Our invention relates to an improvement in fire-escapes; and it consistsin certain arrangements and details of construction hereinafter morespecifically described, and pointed out in the accompanying drawings, inwhich- Figure 1 represents a side elevation of my device; Fig. 2, aperspective view of the basket or car with its attachments; Fig. 3, a

vertical section of the basket. Fig. 4 is a horizontal section throughthe line 00 00 of Fig. 1.

WVe employ in constructing our fireescape a mast, A, of suitable length,size, and material, tapering slightly toward the top, to which the caror basket is secured by rings B B, surrounding and inclosing the mast,and to which the basket is secured in the manner hereinafter described.The rings B B are of a diameter slightly greater than that of the mastat its largest point, to enable them to slide freely along it, andsecured to their inner faccs at right angles are two or more shortmetallic springs, O, in the outer or projecting ends of which aremounted frictionrollers (I, designed to bear against the outer face orsurface of the mast when the rings inclose it. To the lowermost ring, B,the rim of the basket or car is securely bolted, and a connecting-brace,E, is also secured thereto, and extends upward for a suitable distance,and is then bolted to ring B, and bent out ward and bifurcated, and itsbranches E E carried down to the opposite sides or corners of the basketor car and secured thereto, as shown in Fig. 2. The foot of the mast isprovided with a pin or sharp point, z, de-

signed to sink in the ground and prevent the mast from slipping when inposition. Upon the opposite or top end of the mast is a triangular orthree-pointed plate, F, the corners or points of which are perforated toenable guy-ropes to be fitted and secured thereto. Near the top of themast is a slot or opening, in which is fitted a pulley, O, and near thefoot of the mast is mortised or otherwise secured a short bracket orstud, G, projecting at right angles from the mast, and also fitted atits outer end with a pulley, 0. Over and around these pulleys passes arope, D, one end of which is secured to the frame or handle of thebasket,for the purpose of raising or lowering it along the mast when inposition.

iVhen it is desired to operate our device, it is placed in position nearthe building, as shown in Fig. 1, and firmly secured in place by meansof the guy-ropes P, attached to the plate F at the top, and theiropposite ends I at or near the ground. The power is then applied to thelower end of rope D and the car or basket raised to any window or otheropening along the front of the house that it is desired to reach, andwhen loaded is allowed to descend smoothly and safely to the ground byreleasing the tension upon the pulicy-rope D, the springs 0 andfriction-rollers (2 serving to prevent any binding or jar in thedescent.

WVe do not limit our invention to any partic ular form of basket or car,but prefer a metallic basket of the form shown as the safest and mostconvenient. The mast may also be constructed of wood, iron, or any othersuitable material, and of any convenient size or length.

Having thus described our invention, what we claim, and desire to secureby Letters Patent, is

1. In a fire-escape, the combination, with a mast, of theinclosing-rings fitted with the interior projecting springs, havingfrictionrollers in their outer ends, and the basket secured thereto,withmeans for raising and lowering same, substantially as and for thepurpose set forth.

2. In a fire-escape, the combination of the In testimony whereof weaffix our signatures mast A, provided with the plate F,hguyin presenceof two witnesses. ropes P pin 1', and ulleys O O wit the rings 13 1 3,having t-he interior springs, 0, car- 5 rying friction-rollers d, andfirmly united to the basket or car by the brace E E E eon- \Vitnesses:structed substantially as and for the purpose J.
